WILLIAM F. BUCK, OF CHICAGO,

WATER-LEVEL-DEMONSTRATING DEVICE.

To @ZZ cl2/0m it may concern.'

Be it known that I, IVILLIAM F. BUCK, a citizen of the United States, and resident of Chicago, in the county of Cook and State oi' Illinois, have invented a cert-ain new and useful Improvement in lVater-Level-Demonstrating Devices, of which the following is a description, reference being had to the accompanying drawings, which form a part of my specication.

My invention relates more especially to a device whereby the effect of track gradient upon the level of the water in the boiler of a locomotive may be graphically demonstrated; the device being so arranged that the per cent. of grade will be indicated and the eiiect or level of any given gage of water in the boiler demonstrated, as will more clearly be understood from the following detailed description.

In the drawings: Figure 1 illustrates my improved device in front elevation, demonstrating the effect on a given gage oi water in the boiler, when a locomotive is on a level; a port-ion of the supporting frame being broken away. Fig. 2 is a similar view of same, illustrating the eiiect on the given gage of water in the boiler when a locomotive is descending a grade of approximately three per cent.; the lower portion of the supporting frame being broken away. Fig. 8 is a horizontal sectional view taken on the line 3-3 of Fig. 1. Fig. 4 is a detail view of the main or central pivotal point, taken on line 4-4 of Fig. l, looking down. Fig. 5 is a detail view, in section, of a tension device employed in connection with the water level indicating mechanism. Fig. G is a front elevation of a modified construction. Fig. 7 is a top plan view of same. Fig. 8 is a side elevation of same, with the lower part of the supporting frame broken away. Fig. 9 is a detail sectional view taken on the line 9 9 of Fig. 6.

As an exempliication of my invention, I show the device provided with standards or supporting frame 10, of any suitable construction, having the uniting members 11 and 12, and vertically extending member 13. The frame is designed to stand upon the floor, and is made of a suitable height to adapt it to the uses for which the device is intended. A display board or member 14 is pivotally secured at its center of gravity to frame-member 13, by the pintle 15, whichr Specification of Letters Patent.

is secured to the member 14 in any suitable manner; for example, the pint-le 15 is shown provided with a flange portion whereby it may be secured to member 14, while the outer end thereof is shown screw-threaded to receive a nut or washer as shown in Fig. 4; the pintle 15 is preferably passed through a errule or bushing 15, secured within the opening in frame-member 18. Member 14 is intended to be provided with a longitudinal sectional view of a locomotive boiler; this may either be drawn or painted on member 14, or the drawing may be on a separate board or light frame, and secured to member 14.

Pivotally mounted on the plate or upwardly extending lug 1G is a lever 17, which extends adjacent the upwardly extending slotted member 18, secured on cross-member 2 of the frame; and the lever 17Imay be clamped or held in the desired position by the butterfly-nut 19. One end of lever 17 is pivotally secured to link 20, which link is in turn pivoted to carriermember or board 14, at a point intermediate of the pivotal point 15 and one end of the member 14. The other or -lree end of lever 17 is made pointed, so as to act as an indicator in connection wit-h the scale 21, of suitable description, whereby the per cent. of incline or decline of the link-end of carriermember 14 may be indicated. The scale 21 is rigidly secured to upper cross-member 12.

It is evident from the construction shown and described that the adjusted position of member 14 can be maintained by tightening the clamp 19 and holding lever 17 against the quadrant 18.

Pivotally secured to the frame-member 12, by hangers 22, are a pair of levers 23 and 24, whose inner or adjacent ends are united by link 25. 'Ihe outer ends of levers 23 and 24 are provided with the studs or pins 26, which may be screwed into or otherwise secured to the levers 23 and 24. The pin-carrying or outer ends of levers 23 and 24 are arranged in the same horizontal plane, so that a cord or wire 27 which reaches from pin to pin across the face of carrier-member 14 and the drawing secured thereon, will extend in the same hcri zontal plane throughout its length.

In order that the wire or cord 27 may be held taut, in any adjusted position of the levers, I provide a spring tension device 2S.

One end of wire or cord 27 is secured -to 'the end of plunger 29, which is oontrolled'by` the coiled spring 30,-.see Fig. 5-, while a short wire or cord may be passed 'through the eye 3l, and also be secured to vthe .pin 26 at that end of lever 24, as can more clearly be seen in Fig. 3. y

To maintain the 'levers 23 andV 24 in their adjusted positions, andfal-so to permit 'of their easy operation, I extend the end 'of one 'of .the levers, forexample lever 24, so `'as' to form a handle, which is provided with la latch or spring-clamp 32, which engages with the slotted member 33, secured to fthe rame,vas clearly shown in F ig. il.

It is evident from vthe construction, that. when ythe -latch 32 is released from engage' ment with member 33, and lever`24c is swung about its pivotal point,rlever'23 will bemoved f in a similar manner by .reason of Athe flink connection 25' .between the levers, 'thereby' bringing the outer ends of both levers into the same adjusted fhorizontal plane. Vhen tho `ends vof 4the levers are=swung out ofthe horizontal plane occupied by their respective :pivotal points on hangers 22, it is evident that the distance between pins 26, '26, will be altered `or shortened; fthe cord or` wire 27 will however #be lkept taut l'lo'ythe action of spring 30 on the plunger '29 of the tension device 23.

The object of 'the invention is to instruct engineers and others as tothe etfect'on the water 'level fin Vthe boiler when 'the looomoltive ascends `or descends the 'various ygrades encountered by .them on vtheir respective '.fruns; =the :mechanism .fbeing .readily adjust-1. -able so as i-to demonstrate the 4eifect "with varyingrgagesof water.

The carrier 4member or .board lll is provided with'a scale drawing ordiagrammatic 'view 'of fa locomotive boiler as .represented in 'the drawings; 'the drawing being placed `-on member 314; Sin any :of the 'aways hereinbefore described. NVhen .it is desired to .em- .-ploy the device, ythe lboilerfor dra-wing thereof, is adjusted to a ilevel rposition, which may f; be accomplished by swingingfboarcbormember le by 'hand iuntil 'the indicator or send o tf Vlever 17 points to Zero :on1the scale .-21,- which Vindicates 'the gradesras shown .iin Fig. l. The yboard'or member 14 may tbe' 'held iin the desired :position by the clamp- 4ing or'butterfyfnut 19. Havingladij usted the 4boiler-drawing, adjust the position of .co-rd or wire 27 lto the gage l-or Vlwater vlevel idesired ifor 'the 'purpose lof fdemonstration, by '.graspring the end-ofilever 24and latch 32, therebyi :movingthe pins 26 .into thefhorizontal iplane -of the Iwater level desired. VAfter'the Awaterlevel indicating oord or wire 1:has been j usted, clamping nut 19 is then .unscrewed 'so .that board lor lcarrier-member 14 ma-y bei swung fto :indicate fa locomotive either ascending or 'descending a Izgrade, llever :12.75

the front flue sheet. Itis thus apparent that the depth of water over the crown sheetand the changes'duel to the various grades may be Iclearly observed by the use 'of my improved device, as illustrated in Fig. 2,v

wherein the device is adjusted sto demon- .strate the level oli' "the lwaterwhen .a locomotive fis descending la three per fcent. fgrade fas :shown by the scale.

' rlhe-c'levice vmay l'be .altered in annum'ber-of details, fas for example, .in fFigs; 6, 7 ,8, .and

with the fguides 35, 35, whose construction Y isrclearlyshown in Figs. 6 and 8. Afthumb Snut 3G .is .screwed onto a pin 37, which extends ith'rough a slot in the vguides v35 :and a fhole in each end fof Athe Lstraightedge 34, so that the fpin 37 Vmay slide fup .and down lin theslot of =the guides 35, kWhilethe screwing up of nuts 36 will irmly clamp for ho'ld'the straight .edge fin its Aadjusted Aposition, and the upper edge fof 'member 34 will .represent Ithe surface :ofthe 'water in the boiler. The 'operation of :this vconstruction is of 1course similar 4Ito that of .-the construct-ion 'shown -in the previous' figures.

vI have 'briefly :stated .fthe purpose of my invention, :and :have shown and described .i what I 5believe 1to -be the simplest @and 'best constructions, but Ithe y.constructions may 'be altered rin `'certain 'details without departing from fthe spirit iof my invention, =and I fdo :not v'wish f'to be 'understood therefore Yas limiting 'myself to fthe vexact constructions shown and adescribed; but
